I'm so sorry to ask the question like that. Now, I've solve this
problem myself.
My original purpose is to adaptively estimate the frequecies from
noisy harmonic signal.
The subspace methods are seems to be good solutions, such as MUSIC ,
ESPRIT and
so on. In these methods, however, the inverse of convariance matrix
or the eigenvector
of date vectors need to be calculated to get the noise subspace and
the signal subspace.
The computational complexity can be reduced by Multistage Wiener
Filter. But at beginning,
I can't understand the algorithm in J. Scott Goldstein's paper. From
the Michael D. Zoltowski
tutorial (http://cobweb.ecn.purdue.edu/~mikedz/research/
research.html), I got the algorithm's
detail information. Now I'v implemented it with Matlab.
Thank julius for his suggestion!

Rather than asking for the solution, why don't you ask
a more meaningful question, such as what you expect
and what you get.
Right now you come across as somebody asking for
the solution for free, without having tried.

The paper is
Goldstein J Scott, Reed Irving S, Scharf Louis L.
'A multistage representation of the wiener filter based on orthogonal
p rojections'.
IEEE Transactions on Information Theory, Vol.44 Nov.
1998:pp2943-2959.
Who can help me to implement it with matlab?
Thanks!

I've read J. Scott Goldstein's paper 'A Multistage Representation of
the Wiener
Filter Based on Orthogonal Projections' and written a test matlab
program. But it
seems wrong. Who has ever implemented it ?
